Kinetic-Molecular Theory To explain the existence of states of matter and changes of phase, we use a microscopic model of matter. The kinetic theory of matter states that the matter is made up of tiny particles that move all the time. ï· All matter is made up of tiny, invisible, moving particles.
A eukaryote (/juËËkÃ¦ri.oÊt/ or /juËËkÃ¦riÉt/) is any organism whose cells have a cell nucleus and other organelles enclosed within membranes. Eukaryotes belong to the taxon Eukarya or Eukaryota.
Bacteria are microscopic organisms whose single cells have neither a membrane-enclosed nucleus nor other membrane-enclosed organelles like mitochondria and chloroplasts.
